EV Rescue System with Environmental Detection for Safe Power Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicles with low state of charge may be unable to reach the nearest charging station, posing a challenge for power storage device charging without causing inconvenience or risk to the vehicle and its surroundings.
Innovation Solution
A movable body rescue system where a server communicates with electric vehicles to select a power-supplying vehicle to transfer electric power to a depleted vehicle, determining a safe stopping position based on environmental conditions, allowing charging without the need for the depleted vehicle to travel to a charging station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electric vehicle travels to the nearest charging station, then the power storage device can be charged, but the vehicle may be unable to reach the charging station due to low state of charge
Solution Approach 1:
The patent introduces a power supply vehicle as an intermediary element between the depleted vehicle and the charging infrastructure. The power supply vehicle carries a portable power supply device that can directly charge the depleted vehicle's power storage device, eliminating the need for the depleted vehicle to travel to a charging station. This mediator resolves the contradiction by enabling charging without requiring the depleted vehicle's mobility.
2Ease of operation
If the power-supplying movable body stops near the first movable body to supply power, then power transfer can be performed, but it may cause inconvenience or risk to the surroundings
Solution Approach 1:
The patent applies preliminary action by having the power supply vehicle perform detection and determination of the stopping position before actually stopping to supply power. The detection device surveys the surrounding environment, and the stopping position determination unit identifies a safe location that minimizes risk to pedestrians and other obstacles. This preliminary assessment ensures that the subsequent power transfer operation can proceed safely.
Solution Approach 2:
The system uses feedback from the detection device about the surrounding environment to dynamically determine the optimal stopping position. The detection information feeds back into the stopping position determination unit, which adjusts the stopping location based on real-time conditions such as pedestrian presence, road geometry, and potential hazards. This feedback mechanism resolves the contradiction by enabling safe power transfer while considering surrounding conditions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables charging of the power storage device without the vehicle traveling to a charging station, reducing the risk of collision and minimizing inconvenience to the surroundings by determining a safe stopping position for power transfer.
Implementation Method 1
Each of the second movable bodies includes a detection device configured to detect a situation outside the second movable body
Implementation Method 2
the first power storage device can be charged by receiving electric power from any one of the plurality of second movable bodies
Data Source
AI summary
Each vehicle includes a detection device configured to detect a situation outside the vehicle. When a server receives from a depleted EV a help signal requesting power supply from another vehicle to the depleted EV, the server selects, from among the other vehicles, a rescue EV to supply electric power to the depleted EV. The rescue EV moves to the depleted EV, determines a stopping position of the rescue EV from a situation around the depleted EV detected by the detection device, and performs power supply to the depleted EV at the stopping position.
